Description

[Detailed description of the invention] Industrial application field This invention relates to a column-beam joint structure in a steel frame building.

BACKGROUND TECHNOLOGY In recent years, steel frame buildings have tended to have more complex shapes in order to achieve novelty in design, and as a result, H-shaped steel beams are often joined diagonally.

Conventionally, columns and beams in such cases have been joined via column-beam joining fittings (hereinafter simply referred to as joining fittings) formed at each joining location.

Problems to be Solved by the Invention However, joining fittings generally have a special shape, and the joining fittings for joining beams diagonally have particularly complicated shapes and are troublesome to manufacture.

Furthermore, since the joining fittings are usually attached in advance by welding in a factory or the like, they are a nuisance during transportation.

Purpose of the invention This invention was proposed to solve the above-mentioned conventional problems. The object of the present invention is to provide a column-beam joint structure that can be easily and reliably joined.

Structure of the device This device is designed to connect a plurality of H-shaped steel beams to a steel column made of square steel pipes, one of which is vertically connected and the other diagonally. A column-beam joint comprising a fixing part, a vertical connecting part protruding substantially perpendicularly from a substantially central part of the fixing part, and a diagonal connecting part protruding diagonally from an edge of the fixing part. is attached to the steel column by bolting, one H-beam is attached to the vertical connection part by bolting the web of the H-beam, and the other, upper and lower, is attached to the diagonal connection part. The above object is achieved by joining H-shaped steel beams whose flanges have oblique tip ends by bolting the webs of the H-shaped steel beams.

Embodiment Hereinafter, this invention will be explained based on an illustrative embodiment.

H-shaped steel beams 2 and 3 (hereinafter simply referred to as beams 2 and 3) are joined to a column 1 made of a square steel pipe by a joining fitting 4 (see FIG. 1).

The joining fitting 4 is integrally formed from a fixing part 5, a vertical connecting part 6, a diagonal connecting part 7, and upper and lower reinforcing parts 8, 8 (see FIGS. 2 and 3).

The fixing part 5 is formed into a vertically elongated substantially rectangular plate shape, and a plurality of mounting holes 9 are formed in the fixing part 5 at predetermined intervals in the vertical and horizontal directions.

The vertical connecting portion 6 and the diagonal connecting portion 7 are formed in the shape of a vertically long rectangular plate similarly to the fixing portion 5, and the vertical connecting portion 6
protrudes perpendicularly from the substantially central portion of the fixing portion 5, and the diagonal connecting portion 7 protrudes obliquely from the edge portion of the fixing portion 6 at a predetermined angle, for example, approximately 135°.

Further, a plurality of mounting holes 10 are formed in the vertical connecting portion 6 and the diagonal connecting portion 7 at predetermined intervals in the vertical direction and the horizontal direction.

The joint fitting 4 formed in this manner is attached to the beam joint of the column 1, and is attached to the mounting hole 9 of the fixing part 5 in the receiving metal fitting 11 that is previously attached to the inside of the beam joint of the column 1. , 9 are fixed by a plurality of mounting bolts 12, 12 passing through them.

Then, the web part 2a of the beam 2 is attached to the vertical connecting part 6, and the mounting holes 10, 10 of the vertical connecting part 6 and the mounting holes of the web 2a formed corresponding to the mounting holes 10, 10 (not shown) The beam 2 is joined perpendicularly to the column 1 by a plurality of joining bolts 14, 14 passing through.

Further, the web portion 3a of the beam 3 is attached to the diagonal connecting portion 7, and the mounting holes 10, 10 of the vertical connecting portion 7 and the mounting holes of the web 3a formed corresponding to the mounting holes 10, 10 (not shown). The beam 3 is diagonally joined to the column 1 by a plurality of joint bolts 13, 13 passing through the beam.

Further, the tips of the upper and lower flanges 3b, 3b of the beam 3 are formed diagonally so as not to interfere with the upper and lower flanges 2b, 2b of the steel beam 2.

Effects of the invention Since this invention is configured as explained above, it has the following effects.

In a steel structure building, even when a beam is to be joined diagonally to a column, it can be very easily joined using a joining bolt such as a high-strength bolt.

Since the joining fittings can be installed on site using joining bolts, the joining fittings can be removed when transporting the steel frame materials for columns and beams. Extremely efficient.

Since the joining metal fittings have an extremely simple shape, they can be standardized, and manufacturing costs can be reduced through mass production.

In addition, since the tips of the upper and lower flanges of one beam are formed diagonally so as not to interfere with the other beam, it is possible to bring the end of one beam close to the back of the joint so that it can fully reach the column. Therefore, one beam can be reliably joined to the column, and the joining fittings can also be small.
